Error in at least 4.13.0 and 4.13.1 on PC build for GearVR.
Problem 1:
Situation: .mp4 are playing on a Media Texture on a canvas mesh.
When you look away from the canvas while the movie still running → parts of raw movie are superimposed onto the view, like a 2d element linked to the camera. I can say raw because my movies are graphics on a black background, the material set to add so they appear like light painted onto the canvas-objects inside my scene. The graphic glitches show the black-based movies not something transparent.
Problem 2:
Error only in 4.13.1 NOT in 4.13.0
Situation: .mp4 are playing on a Media Texture on a canvas mesh.
Movies end prematurely during play, there is no stop play command or hide canvas whatsoever.
Once “crashed” commands to reload movie into media player / rewind don’t play the video any more.
This one forced me to switch back to 4.13.0 and compile myself 4.13.0 for actual GearVR projects.
I can send in a demo project, but it has to be confidential so no public link here.
If you would like to provide your project privately you can do so by sending it to me in a private message on the forums. This can be done by provided a google drive or dropbox link.
I’ve send you the project over pm on the forum. Did you found sth out?
Packaged with 4.13.1 it also has a high probability to crash on level load (change of room) on the GearVR.
A: ERROR in 4.13.0 and 4.13.1: movie appear randomly over the screen and not on the designated mesh canvas.
B: ERROR in 4.13.1 Movies end prematurely during play, there is no stop play command or hide canvas whatsoever. Once “crashed” commands to reload movie into media player / rewind don’t play the video any more.
C: ERROR in 4.13.1: app is crashing on 7 of 10 Samsung S7s on first level/room load
Our customer is using multiple Samsung S7 European and Australian versions (if they are different?) with the last white GearVR version.
Errors are only after packaging and delivering for GearVR on the S7s.
A: Packaged with 4.13.0: Gaze-activate the first movie in the start-level. Rotate your head about 120° or more to the left away from the canvas while the movie is still running → the raw movie is superimposed onto the view, like a 2d element written into the frame-buffer, every movie in app show this error.
B: Packaged with 4.13.1: Gaze-Activate the movie in the first room an wait a few seconds. Movie should play for over 20 seconds, but it ends prematurely. After regulat play time when the icons reappear, try to replay it, it won’t work anymore.
C: Packaged with 4.13.1: Gaze-Activate the arrow beside the door to change the room, App will crash on first level-change with chance of about 70%-80% or runs for longer time without crashes on following level-loads.
After further testing I was able to reproduce one on the issue that you are experiencing. The issue with the video becoming stuck on the screen after looking away. This is a known issue (I have provided a link below). However, the project did not crash on the device nor did the movies appear to end early.
Ok, I’ve managed to get rid of the error, but I don’t know how. I didn’t changed something Media player/texture/blueprint/canvas specific in my projekt or my development machine. Perhaps a S7 Android/Oculus update fixed it. Thanks for the work guys.
